What is the meaning of variable #103 in your tool change macro? Your code fragment above references it, but must assume it was set somewhere previously.

The code fragment above seems to assume that #101 is equal to the current turret position (approximately 1 - 16).

Ignoring the mystery of #103 ...

Just when I thought I had the atc turret on my lathe figured out.. :lol:

The lathe uses a ratchet and pawl style turret so it has to reverse to lock. its stepper driven, with a current limit set to 20% so it can stall on reverse and not break anything. for the macro, theres a snippet of it below ...

There are nor A values in the lathe tool lib, only X and Z but you can use #2700 for the thrid axis WCS, #2800 for forth axis WCS ect.

Thanks for the response. I figured out what I needed through resolving another issue.
What I needed was a way to force the ...

I've recently done a similar implementation and one many years ago before the wizards were there to help.

Key things to get right to get it to work.

1. Ensure that your turn ratios suit. In other words, ensure that it 'clicks' 8 times on 8 tool moves. I opened mine and manually moved it to see ...

Hello all.

Has anyone figured out reliable lock up on a stepper driven ratchet and pawl style ATC lathe turret??

I have it set up as an "axis driven turret" with appropriate "move past" and "reverse" parameters set but it still isn't reversing until stall on every tool change.. It will stall on ...

G10 P1 Z0.1 is setting the Z offset to 0.1 as an absolute value.

If you want to incremental increase the offset +0.1 use : G10 P1 Z[#11001+0.1]

Thanks for taking the time to help! this helped move the project along but hit another snag..
Looks like I'm assigning the project to axis to "A ...

Alright
I'm back to ask more stupid questions... Beware LOL

Without getting into the weeds on details of use, I'm writing a macro to automate a repeat task... part of it involves adding an incremental offset to an auxiliary axis. It looks like G10 can do what I need but its syntax and function ...

Hello!

TLDR: I need some help editing the attached macro so the stepper driving the ATC, backfeeds until it stalls on every tool change. at present, it only stalls on back feed on the first tool change. Maybe the back feed line needs to be changed to incremental and the TC value is forced to the ...

So..

to document this for anyone that runs into the same problem... At least on CNC12 V5.20... manually editing parameter 33 with the high gear ratio and changing parameter 36 bit 4 is a thing and best yet...

THIS WORKED.. without having to splice in a an index sensor on a line driver chip ...

OK so..

Dumb question..
What if I set Parameter 33 to 2, to match the 2:1 gearing between the motor and my encoder..
Then set parameter 36.. bit4 should be motor side encoder. with rigid tapping off the value should be 16..

I only use 1 gear ratio so I don't think it will affect anything else ...
